Black Goji Berry Extract
Introduction
Harvested from the harsh, high-altitude, and high-salinity extremophile environments of the Tibetan Plateau and surrounding basins, Black Goji Berry (Lycium ruthenicum) survives by biosynthesizing extraordinary levels of protective polyphenols. It is globally recognized as one of nature’s most dense sources of both wild Anthocyanins (particularly petunidin derivatives) and Oligomeric Proanthocyanidins (OPCs). The industrial challenge is that extreme heat during extraction destroys these delicate macromolecular chains. Shaanxi Runke solves this by deploying cold-water maceration combined with advanced low-temperature membrane filtration. This zero-heat process preserves the intact structural integrity of the OPCs, yielding a bioactive ingredient with an exceptionally high ORAC (Oxygen Radical Absorbance Capacity) value, engineered explicitly for the luxury "beauty-from-within" sector.

Benefits
The high levels of OPCs actively scavenge free radicals, protecting cellular DNA and lipids from oxidative stress. Its ORAC (Oxygen Radical Absorbance Capacity) value is among the highest of any known botanical extract, effectively combatting cellular aging.
Ocular Health & Vision Support:
Similar to Crocetin and Lutein, the specific anthocyanins in Black Goji cross the blood-retinal barrier. They promote the regeneration of rhodopsin in retinal cells, reducing digital eye fatigue, improving night vision, and protecting the macula from UV and blue light damage.
Skin Rejuvenation (Nutricosmetics):
By inhibiting the enzymes elastase and collagenase (which break down skin structure), the extract protects the skin's collagen network. This "beauty-from-within" mechanism helps reduce wrinkle formation, improves skin elasticity, and mitigates UV-induced photoaging.
Cardiovascular & Microcirculation Health:
The bioactive OPCs strengthen capillary walls and improve endothelial function. This enhances blood circulation, regulates blood pressure, and supports overall cardiovascular homeostasis.
Applications
Highly prized in the beverage industry not just for health benefits, but for its pH-dependent color-changing properties. It acts as a natural, interactive dye—turning a vibrant pink/magenta in acidic environments (like lemonade) and a striking blue in alkaline solutions (like mineral water). Perfect for RTD teas, sports drinks, and premium vitamin waters.
Dietary Supplements:
Encapsulated in hard shells or formulated into softgels, tablets, and functional gummies targeting anti-aging, vision support, and immune system fortification.
Nutricosmetics & Skincare:
Used as an active ingredient in "beauty-from-within" stick packs, collagen companion formulas, and topical antioxidant serums designed to combat oxidative skin damage.
Functional Foods:
Incorporated into nutritional energy bars, yogurt preparations, and health-focused baked goods for both its nutritional profile and natural purple pigmentation.
